About This Webinar... TITLE: Anaerobic Bioremediation System Optimization SPEAKER: Stephen Richardson, Ph.D., P.E. DATE: May 9, 2013 TIME: 12:00PM EDT For optimized anaerobic biodegradation, better treatment requires better contact between the substrate and the contaminant. But how does one improve contact without ...

After injection of a hydrogen-releasing compound reduced the plume by 50%, a hydrogen gas infusion system (iSOC®) was installed at the former Defense Property Disposal Office (DPDO) Waste Storage Area to maintain favorable conditions for the anaerobic bacteria. By enhancing reductive dechlorination (keeping the bacteria happy), solvent concentrations at the infusion wells were reduced by 93% ...

Tersus Environmental announced today that the United States Patent and Trademark Office granted a patent for soil or groundwater remediation using a self-nanoemulsifying oil. The issuance of this patent further validates the innovative nature of Tersus' electron donor technology platform and family of biotechnology-based solutions to manage complex, challenging environmental liabilities. ...

Dr. Robert Borden, P.E., Principal Engineer at Solutions-IES, Inc., explains the basics of anaerobic bioremediation. Questions to be addressed include: What is anaerobic bioremediation? Why use anaerobic bioremediation? What is an electron donor? Which substrate is required? What are ...

REGENESIS, a leading innovator of advanced, costeffective groundwater and soil remediation technologies, was recently granted U.S. Patent 7,667,062 for 3-D Microemulsion (3DMe), a proven groundwater remediation technology specifically designed to penetrate and treat aquifer systems unlike any other anaerobic bioremediation material on the market today. Other related U.S. and international patents ...

The legacy of nuclear weapons and nuclear energy development has left ground water and sediment at dozens of sites across the United States and many more around the world contaminated with uranium. The uranium is transported through ground water as uranyl (U6+). In one bioremediation strategy, uranium immobilization in contaminated ground water and sediment may be achieved by the addition of ...

Past use of tricholoroethene (TCE) at a manufacturing facility in Indiana created a contaminated plume of groundwater approximately 1,000 feet wide, 8,000 feet long, and up to 75 feet deep. The plume has impacted a regionally significant unconfined aquifer. EOS® 598B42 was the selected electron donor for the bioaugmentation pilot test that was completed at the site. The pilot test demonstrated ...

To complement its Gas inFusion technologies, Tersus Environmental unveiled today a new family of products for enhanced in situ bioremediation. The new products are engineered to treat soil and groundwater contaminated with organic constituents amenable to anaerobic bioremediation processes, including chlorinated solvents, energetics and pesticides/herbicides. These amendments from Tersus can also ...

Project: EHC® Treatment of Chlorinated Ethenes, Ethanes, and Methanes in Saprolite Soils and Partially Weathered Rock, Manufacturing Facility – Western NCSummary:Field scale pilot tests were performed to evaluate the performance of enhanced reductive dechlorination (ERD) of chlorinated aliphatic hydrocarbons (CAHs) at a manufacturing facility in western North Carolina. The key CAHs found in ...

Bioremediation Consulting Inc. (BCI) Announces Development of the First Commercial Culture to Degrade Highly Chlorinated Polychlorinated Biphenyls (PCBs) Bioremediation Consulting Inc., Watertown MA announced the completion of a research project funded by a Small Business Innovation Research (SBIR) grant from the National ...

The short course will provide an understanding of how EOS® can be used to stimulate anaerobic biodegradation, how oil droplets are transported and retained in the subsurface, the most effective designs, and efficient approaches for injecting emulsions in the field. The course will begin with an overview of the principles of anaerobic bioremediation, followed by a presentation of colloid ...

BCI Wins NSF Award to Develop PCB- Degrading Bacterial Culture Bioremediation Consulting, Inc (BCI) of Watertown, MA announced today that it has received a Small Business Innovation Research (SBIR) grant from the National Science Foundation. Principal Investigator, Dr. Margaret Findlay will lead BCI's research effort on the development of a commerical ...

EOS Remediation’s family of innovative and sustainable products for enhanced bioremediation will be featured in numerous presentations and posters at the 2011 Battelle International Symposium on Bioremediation and Sustainable Environmental Technologies in Reno, Nevada (June 27-30, 2011). We are proud that our products span a wide variety of disciplines at this year’s conference ...

Thu, Aug 1, 2013 1:00 PM - 2:00 PM EDT Anaerobic degradation is the dominant process in natural attenuation of hydrocarbon contamination in the subsurface. We will start with an overview of simple geochemical parameters that may be used to show that anaerobic degradation is occurring and enhancement is feasible. Proven extremely effective in enhancing ...

Tetrachloroethylene (PCE) is a problem contaminant because of its widespread use, potential toxicity and persistence in the environment. Like other chlorinated solvents, remediation of PCE in soil and ground water has proven to be very difficult. While there has been has been widespread success under anaerobic conditions, the application of bioremediation under aerobic conditions has not been as ...
